It is generally reported that the grain growth in high-entropy ceramics at high temperatures relatively slower than corresponding single-component owing to so-called sluggish diffusion effect. In this study, we report a fast phenomenon (La0.2Nd0.2Sm0.2Eu0.2Gd0.2)MgAl11O19 (HEMA) prepared by conventional solid-state rea...

the cellular automata method has been used to simulate the pattern formation of the schlögl model as a bistable reaction-diffusion system. both microscopic and macroscopic cellular automata approaches have been considered and two different methods for obtaining the probabilities in the microscopic approach have been mentioned. the results show the tendency of the system towards the more stable ...

the electrocatalysis of the oxygen reduction reaction (orr) on carbon supportedpt-v (1:1) catalyst in polymer electrolyte fuel cells (pefc) was investigated. atan oxygen pressure of one atm an enhanced electrocatalytic property of pt-v/ccompared with pt/c is revealed. these results indicate the occurrence of adifferent electrocatalytic mechanism for the orr on pt/c and pt-v/c. anincrease of mas...

A rapid electrochemical analysis of sulfadiazine (SFZ) has been carried out by cyclic voltammetry (CV) and differential pulse voltammetry (DPV) methods by employing a sensitive single walled carbon nanotube-molybdenum disulfide nanocomposite/poly ethylene glycol modified carbon paste electrode (SWCNT-MoS2/PEG/CPE). The SFZ shows anodic peak potential at 0.94 V (vs. Ag/AgCl) in 0.1 M PBS of pH 7...
